CR6002AB Equivalent & Substitute Parts

Part Overview

The CR6002AB is a Transient Voltage Suppressor (TVS) diode manufactured by Littelfuse Inc., designed for general-purpose voltage clamping applications. This component features a bidirectional 2-channel configuration in a TO-220 Modified package with a reverse standoff voltage of 275V and minimum breakdown voltage of 350V. The CR6002AB is classified as obsolete, making identification of suitable substitute components essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CR6002AB is determined by the following critical parameters:

Primary Substitution Criteria:

• Voltage rating compatibility: Reverse standoff voltage of 275V and breakdown voltage minimum of 350V
• Package compatibility: 3-SIP / TO-220 Modified form factor for direct mechanical and electrical fit
• Bidirectional protection capability: 2-channel configuration for symmetric voltage clamping
• Mounting type: Through-hole technology for PCB integration
• Operating temperature range: -55°C to 175°C (TJ)

Secondary Considerations:

• RoHS compliance status for regulatory alignment
• Moisture sensitivity level (MSL 1 indicates unlimited shelf life)
• Current handling specifications where applicable

The P6002ABL qualifies as a substitute based on matching voltage specifications (275V off-state, 350V breakover), identical package configuration (3-SIP / TO-220 Modified), through-hole mounting, and compatible operating temperature range. The P6002ABL represents an active product from the same manufacturer, providing long-term availability and regulatory compliance advantages.

Engineering Selection Recommendations

The P6002ABL is the designated manufacturer substitute for the obsolete CR6002AB. Selection of the P6002ABL provides the following advantages:

Product Status: The P6002ABL maintains active product status with Littelfuse, ensuring continued availability, technical support, and supply chain reliability. The CR6002AB obsolescence status creates long-term sourcing risk.

Regulatory Compliance: The P6002ABL achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The CR6002AB's RoHS non-compliant status may present obstacles in regulated industries and future procurement cycles.

Electrical Compatibility: Both components share identical voltage specifications at the 275V/350V operating point, ensuring direct functional equivalence for applications designed around the CR6002AB baseline parameters.

Package Compatibility: Identical 3-SIP / TO-220 Modified packaging enables direct PCB-level substitution without layout modifications or mechanical redesign.

Temperature Performance: Matching operating temperature range (-55°C to 175°C TJ) ensures thermal performance parity across the full operational envelope.

For new designs or system refreshes, the P6002ABL is the appropriate selection. For legacy system maintenance where CR6002AB inventory exists, the P6002ABL provides a forward-compatible upgrade path.

Frequently Asked Questions (FAQ)

Q: Can the P6002ABL be used as a direct replacement for CR6002AB in existing designs?

A: Yes. The P6002ABL matches the CR6002AB in reverse standoff voltage (275V), breakdown voltage (350V), package configuration (3-SIP / TO-220 Modified), and operating temperature range. No circuit modifications are required for direct substitution.

Q: What is the primary difference between CR6002AB and P6002ABL?

A: The CR6002AB is an obsolete Zener-type TVS diode. The P6002ABL is an active SIDACtor® thyristor-based TVS device from the same manufacturer. Both provide equivalent voltage clamping at the 275V/350V specification point. The P6002ABL offers ROHS3 compliance and active product status.

Q: Are there any package or pinout differences?

A: No. Both components use the 3-SIP / TO-220 Modified package with identical mechanical and electrical pinout. PCB footprints are directly compatible.

Q: What is the moisture sensitivity level, and does it affect storage?

A: Both components carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. Standard dry storage conditions are sufficient; no special desiccant or controlled humidity storage is required.

Q: Does the P6002ABL support the full operating temperature range of the CR6002AB?

A: Yes. The P6002ABL operates across -55°C to 175°C (TJ), matching the CR6002AB specification exactly.

Q: Why is RoHS compliance important for this substitution?

A: RoHS compliance ensures the component meets current environmental regulations and facilitates procurement in regulated industries. The P6002ABL's ROHS3 compliance provides regulatory alignment for new designs and future system certifications.

Q: Can I use the P6002ABL in applications requiring the 550V or 700V ratings?

A: The P6002ABL is available in multiple voltage configurations (275V/550V and 350V/700V). Verify the specific part number variant matches your application voltage requirements. The standard P6002ABL substitute for CR6002AB operates at the 275V/350V specification point.
